To all 2071 am it may concern:

Be it known that I, FORREST A. HEATH, a citizen of the United States, and a resident of the city of Jersey City, in the county of Hudson and State of New Jersey, have 1nvented certain new and useful Improvements in Mixing Devices, of which the following is a specification.

The invention relates to mixing or commingling devices for mixing or commingllng a mixture such as comes from a carburetor and is to be utilized in the cylinder of a hydro-carbon engine.

In a broad aspect it relates to a devlce which efiects the mixing or commingling of the elements in the mixture by the movement of a member having stepped relation blade elements moving transverse the path of the mixture and by the movement of which member the mixture which is engaged with one blade element is segregated by a succeeding blade element.

The invention particularly relates to that type of device in which the mixture or commingling is eflected by fan blade elements arranged in stepped relation which are rotatably mounted in a casing and which are arranged along the axis of rotation in such manner that the mixture passing over one blade element is segregated by the succeeding bladeelement.

As showing a specific embodiment thereof reference is made to the drawings forming a part of the specification and in which,

Figure 1 is a view looking upward at the bottom of one form of mixing or commingling member. Fig. 2 is a side elevation of form shown in Fig. 1 with two sets of blade elements arranged in stepped relation as indicated in dotted lines. Fig. 3 is a transverse sectional view of the rim and the ends of two sets of blade elements taken on the line 33 of Fig. 1. Fig. 4 shows in plan a mixing or commingling device with a mixing or commingling member of a different form from that shown in Fig. 1. Fig. 5 is a side view of the mixing or commingling member shown in Fig. 4 with two sets of blade elements arranged in stepped relation as shown in dotted position. Fig. 6 is a section on lines 66 showing the blade elements which are cut tive the rim. Fig. 7 line 77 of Fig. 4.

In the form shown in Figs. 1 to 3 the mixing or commingling member is designated by reference character a. This member has the ring I), rim 0 and sets of blade elements d. All of the blade elements 6, f, g and h which constitute each set are carried by the ring Z) and part of the blade elements of the difl'erent sets namely 72, are connected to the rim and support the same. It is obvious, however, that all of the blade elements could be connected to the rim or that at least a part of them could be carried by the rim instead of the ring.

In Fig. 4 is shown a mixing device in which the member above described may be used, but in this figure a mixing or comn1ingling member of a difi'erent form is shown. Both the mixing members however possess the same underlying characteristics as will presently appear.

In Figs. 4 and 7 the mixing or commingling device is designated by A having a casing B provided with a web 0 in which is secured the pin D held in place by screw engagement with the web and locked therein by nut E. The lower end of pin D has a head which serves as a race-way for the lower set of balls of ball bearing F. This bearing has two sets of balls between which is located the hub G secured to the mixing or commingling member a. The member a has a ring 6 similar to the rim 6 in Fig. 1, a rim 0' and an arm extending laterally between and integral with the ring and rim, carrying segments d each of which seg ments comprises a plurality of blade elements 6, f, g and h with openings between the blade elements. The adjacent blade elements in each segment have connections extending therebetween preferably at the ends of the blade elements but they may be at other points.

It will be observed that there is a structural feature common to both forms as shown in Figs. 1 to 3 and 4 to 7 and this is the stepped relation of the blade elements of each set (or segment as called in the description of Figs. 4 to 7). From a careful and their position rela 1s a transverse view on the blades or blade elementsptarebaused move by, the mixture engttgingthereyvitha comparatively large number of fan blade elements without having a large number of blades or blade elements at any one transverse plane through the mixing member. This feature would apply results to any member which moves transverse the path of the mixture for producing a com-mingling of the elements of a mixture of the class mentioned as long as the stepped arrangement of the blade elements is maintained and so long as the bladex 'elements of each set are arranged along the direction in which the mixture flows. While the invention is applied to a m xing device in which still it is to be understood that it""is' applicable to adevice in which the mixing member is caused to be operated by an outside source of power and that such structure would be within the scope of the invention and it is obvious that various other forms and modifications may be made without departing from the spirit and scope of my invention.

I claim as my invention:

1. A rotary member for mixing devices having fan blade its length in stepped relation with openings between the elements.

2. A rotary member having sets of fan blade elements, a succeeding fan blade element having a portion at one side of the surface of the fan blade element which precedes the same, which portion is offset to segregate mixture which has been in'contact with said surface from the rest of the mixture.

3. A rotary member for mixing devices raving sets of fan blade elements around its axis, the blade elements of each set being arranged in'stepped relation to one another with equally good elements arranged along for mixing devices magma and provided with openings or spaces therebetween.

1. A rotary member for mixing devices having a hub and carried thereby sets of fan blade elements, each element having a cutting edge which projects beyond the face of the fan blade element preceding the same and openings or spaces between said element through which mixture segregated by the portion can pass.

5. In a mixing device a rotary carrier having a number of fan blade elements the blade elements being arranged one behind the other in the direction of transit of the mixture and so that a portion of the mixture which engages one of the blade elements will be segregated by the succeeding blade element and pass behind the same.

6. In a mixing device the combination of a casing having walls which define the path of the mixture and a mixing or commingling member mounted so as to move transversely thereof, said member having inclined blade elements arranged along the path of the -mixture which elements are stepped relative to one another with openings or spaces therebetween, said blade elements also so' arranged that the portionof the mixture which is in engagement with one of the blade elements will be segregated by a succeeding blade element.

7 In a mixing device of the class described, a rotatable member having groups or sets of fan blade elements which elements are arranged in' stepped relation in each group.

8. A rotary member comprising a rotatable central supporting member carrying sets of fan blade elements which are arranged in stepped relation, the last "blade element of one set being arranged so that one edge thereof issubstantially over an edge of the first blade element of the succeeding set, there being no fan blade elements between the sets.
